Description of sunflower oil making machine:
1. Sunflower oil pretreatment and pressing machine introduction:
First, using cleaning machine to remove metals, small stones , impurities from sunflower raw seeds.
Second, using husking machine to remove husks, separating screen to separate husk and sunflower kernel.
Third, crushing , softening , falaking, cooking sunflower seeds ready for sunflower oil pre-pressing process.
Fourth, pre-pressing sunflower seeds. here only pre-press part of sunflower oil , oil residue inside cake (about 12-16%) will be extracted in sunflower oil extraction process.After pre-pressed, the crude sunflower oil will be delivered directly to sunflower oil refining workshop, and pressed cake to sunflower oil extraction workshop.

2. Sunflower oil solvent extraction process:
 |
| Sunflower oil solvent extraction plant |
First, using solvent to extract oil from sunflower oil cake inside oil extractor, final products are mixed oil and wet meal
Second, the mixed oil will pass through three evaporators to make solvent inside transform into gas , and solvent will be recovered through condensers and reused. These three evaporators are not with same size , the first evaporator is bigger than other two because there are more solvent inside mixed oil in the beginning . After evaporated, we will get crude sunflower oil ready for oil refining.
Third, the wet meal will be delivered to desolventizer to dry and be separated with solvent . The dry meal will be packaged for sale as animal feed.
Note: Sunflower oil extraction is more and more important in oil processing , because oil residue inside meal is less than 1% much less than oil residue inside cake without extraction.
3. Sunflower oil refining process
Sunflower oil refing process flow diagram:
Crude sunflower oil → degumming →deacidification → decolorization → deodorization → dewaxing → final sunflower oil

| Sunflower oil refining process |
Sunflower oil refining process description:
First , hydrated degumming, mainly is to remove phosphatide inside crude sunflower oil in order to reduce oil loss and improve quality of oil .
Second, alkali refining, using alkali to neutralize free fatty acid with by-product of soapstock ,which is used for making soap.
Third, decoloration using bleaching clay to absorb darker colorant inside crude oil.
Fourth, deodorization is using high temparature to remove the impurities with bad smell .
Fifth, dewaxing is using low temperature to freeze wax inside refined oil and then separate wax with diaphragm filter.
